Abstract:

Objective To investigate the effect of side⁃opening cannula（SOC）percutaneous vertebroplasty （PVP）in the treatment of osteoporotic vertebral compression fractures（OVCFs）. Methods A retrospective analysis of the clinical data of 118 cases of thoracolumbar OVCF in our hospital from January 2018 to January 2020 was conducted. Patients were divided into SOC PVP group（SOC group），unilateral traditional PVP group（uFOC group）and bilateral traditional PVP group（bFOC group）. Bone cement leakage and distribution，clinical efficacy and prognostic indicators in the three groups were compared and statistically analyzed. Results The bone cement leakage rate in the SOC group was lower than that in the FOC group. The bone cement distribution score and the im⁃ provement rate of Cobb angle 6 months after the surgery were higher in SOC group and bFOC group than those in uFOC group. The incidence of refracture in SOC group and bFOC group was lower than that in uFOC group and the difference was statistically significant（P < 0.05）. There was no significant difference in the improvement rate of Cobb angle 3 days after operation，VAS and ODI at each time point（P > 0.05）. Conclusion SOC PVP can achieve satisfactory surgical results for OVCFs and it has obvious advantages in improving bone cement distribution and reducing leakage rate.
